Best female vocals on CD

If no one has mentioned the obvious, Tracy Chapman's first CD has great vocal work and not a bad song on the disc, unlike her later and weaker efforts.(material-wise- her voice always sounds great).
Heck, I remember using it to A-B some B& W and Vandersteens I was deciding between.(P.S. Got the Vandy's.)
Most of the rest have been mentioned, I think, but it is worth having Miles Of Aisles as well as the later Joni CD to hear the beauty of her voice earlier, and now the beauty of her interpretation later.

Going to get booted for this one! but what about Reba McEntire.... she just makes me very content. (showing my age now). Maybe with your help, I will outgrow this!

Reba is one of a handful of the very best non-classical singers in the last 30 years. Wonderful voice and knows how to use it. Only problem is the materal she chooses to sing. I still have several of her lps, but have never bought one of her cds.

Every collection needs Amanda McBroom (Dreaming).

Janis Ian and Anna Caram are among the most gifted female vocalists I have heard. Ofcourse, many of those previously mentioned are wonderful; Sara M, Margo T., Baez....
